Normally, when test AC products, a power meter is
needed to connect between AC power supply and DUT in
series. Since power meter is built-in in IT7300, user don't
need to connect an extra power meter. It is not only easy
for test, but also save cost.

Linear Amplifier Technology
IT7300 series AC source adopts latest linear technology which
greatly reduce the output noise and ensure high working stability.
Because of the lower ripple index, this series AC source can
assist user to get a more precision measuring result.
Multi-function and high precision measurement
Step mode
IT7300 series AC source uses advanced DSP circuit to get higher
precision and high-speed measurement for ture RMS voltage,
true RMS current, true power, frequency, power factor and peak
value. In addition, its high resolution 0.01W/0.1mA extends the
application for Energy Star testing standard. IT7300 series is not
only a AC source, but also a powerful meter.
Pulse mode
Adjustable phase angle
User can set the start and stop phase angle within range of
0~360°.This function is widely used for startup and shutdown
current impact test or various rectifier performance test
List mode
Power line disturbance simulation function
IT7300 series provides powerful functions to simulate all kinds of
power line disturbance conditions. The STEP and PULSE modes
offer a method to execute a single step or continuous output
changes. The LIST Mode, up to 100 sequences, extends this
function for more complex waveform generator needs. In this
way, IT7300 series is capable of simulating all sorts of voltage
dips, surge or trapped wave. The IT7300 series enables users to
perform the pre - compliance tests against IEC 61000-4-11 and
compliance test against IEC 61000-4-14/-4-28 immunity test

Built-in communication interface
An easy-to use rotary knob and self-guiding keypads allow you to set
the output at your desired value without any effort. In addition, IT7300
series AC source has built-in RS232/USB/GPIB/LAN interface,
providing customer high speed and stable communication quality.
Note: IT7321 do not have GPIB interface
TRIAC Dimmer simulation function
ITECH is the pioneer of TRIAC Dimmer function. This function is
used to do dimming and speed regulating test for lamp or
electric motor to ensure the products work well when controller
of dimming and speed regulating is needed.
lT7300 software
lT7000 software offers sweep test, list test, quick setting, phase
dimmer test, report and save the data.
Front phase dimmer
High stability
Based n professional high anti-environment disturbance
technology, self-diagnosis design and OCP/OPP/OTP protections,
this series power supply could work well even in bad
environment. IT7300 AC power supply assists engineer to
ensure quality for products.
Back phase dimmer
SWEEP function
This function tests efficiency of switch power supply and gets
voltage and frequency value at max power. It could change
voltage and frequency by setting start voltage value, end voltage
value, stepping voltage value, start frequency, end frequency,
stepping frequency and time of each step. Time unit of each step
could be S, M, H. And it saves 10 files at most voltage,
frequency and current of max power will be displayed when th
is over.

*There are three levels of current, L-level, M-level and H-level. If Ipeak>300%(Full rms), low level will change to high level; if Ipeak<20%(full rms), M-level will change to L-level; if
Ipeak<80%(full rms), H-level will change to M-level.
